Abstract
An automobile wheel bolt installation structure is used for solving the problem that an automobile wheel bolt and a knuckle interfere when the automobile wheel bolt is changed. The installation structure comprises the knuckle, a flange and automobile wheel bolts. The flange is installed on the knuckle in a pressed mode, and the automobile wheel bolts are arranged in bolt holes which are evenly distributed in the flange. Each automobile wheel bolt comprises a bolt head, a knurl stud, a transition cone surface and a stud. The automobile wheel bolt installation structure is characterized in that a place of the outer wall of the knuckle corresponds to the automobile wheel bolts and is a continuous and smooth arc surface, and the bolt heads of the automobile wheel bolts are in a shape like a cylinder with one corner which is cut off partly. In the automobile wheel bolt installation structure, outer structures of the automobile wheel bolts are improved, so that the knuckle does not need to be provided with a demising groove. Accordingly, the structure of the knuckle is improved, and space positions between cooperate parts are optimized. In addition, the follow-up manufacturing difficulty of the knuckle is reduced, working efficiency is improved, and manufacturing cost is lowered.
Description
Technical field
The utility model relates to a kind of automobile component, and particularly automotive wheel bolt mounting structure belongs to automobile technical field.
Background technique
The assembling of automotive wheel generally is that wheel bolt is installed on the flange plate, and flange plate is fitted on the knuckle, and then automotive wheel is installed, and is by wheel bolt that wheel is fastening again.Wheel bolt can get rusty because of screw thread after using a period of time, damage and need it is changed.Changing wheel bolt need to resign from office wheel bolt from the flanged disc assembly of knuckle, reinstall new bolt, therefore needs at the flanged disc assembly of knuckle enough wheel bolts to be set and withdraws from the space.If it is inadequate that wheel bolt withdraws from the space, then changing needs to scrap case, bearing, flange plate and knuckle in the wheel bolt process, and cost increases greatly.Because of the space of knuckle and flange plate, wheel bolt very narrow and small, withdraw from problem for solving wheel bolt, currently used method is at knuckle the groove of stepping down to be set, so that when needing to change wheel bolt, can under the condition that does not affect other component, wheel bolt be withdrawed from or insert along the groove of stepping down.The problem that this way exists is: after on the knuckle groove of stepping down being set, just need the filling thickening if guarantee knuckle intensity, this is to knuckle light-weight design obstacles; The arranging of groove of stepping down increased the difficulty of the operations such as knuckle rough-cast, machining, and cutter is interrupted cutting during such as machining, has a strong impact on cutter life and work efficiency, causes processing cost to increase.
The model utility content
The utility model is used for solving the defective of above-mentioned prior art, provides to need not to arrange the groove of stepping down on a kind of knuckle, thereby reduces the automotive wheel bolt mounting structure of knuckle difficulty of processing.
The alleged problem of the utility model is solved by following technological scheme:
A kind of automotive wheel bolt mounting structure, it comprises knuckle, flange plate and wheel bolt, described flange plate is fitted on the knuckle, wheel bolt is positioned at the bolt hole that is distributed on the flange plate, wheel bolt is comprised of bolt head, annular knurl double-screw bolt, the transition conical surface and double-screw bolt, it is characterized in that: the corresponding wheel bolt of described knuckle outer wall place is smooth continuous arc surface; The bolt head of described wheel bolt is shaped as cylindrical body and is cut and to have cut a unfilled corner.
Above-mentioned automotive wheel bolt mounting structure, described bolt head unfilled corner place consists of by cutting to cut the inclined-plane and to scabble face with its cutting of intersecting, and cuts the inclined-plane and wheel bolt axis angle α is 40-43 ° for described section, and described section to scabble face parallel with the wheel bolt axis.
Above-mentioned automotive wheel bolt mounting structure, described section is scabbled face to wheel bolt axial line distance and annular knurl double-screw bolt radius coupling, and described bolt head thickness B is of a size of the 6.5-7 millimeter.
The utility model is for needing to arrange the groove of stepping down on the existing automotive wheel bolt mounting structure knuckle, cause the problem that difficulty of processing increases, processing cost raises to be improved, with the cylindrical bolt head of the wheel bolt part of pruning, reduce bolt head overall sizes, thereby need not the purpose that the default groove of stepping down just can be changed wheel bolt on the realization knuckle, and bolt head is pruned and can not had influence on the use function of wheel bolt after the part.The utility model is through improving the automobile bolt external structure, make knuckle that the groove of stepping down needn't be set, therefore improved slewing journal structure, optimize spatial position between each component, reduced simultaneously knuckle following process difficulty, improved work efficiency, reduced processing cost.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is common wheel bolt arrangement schematic representation;
Fig. 3 is the utility model wheel bolt structural representation;
Fig. 4 is the left view of Fig. 3.
Attached number in the figure is expressed as follows: 1. knuckle; 2. flange plate; 3. wheel bolt; 3-1. bolt head; Cut the inclined-plane 3-1-1. cut; 3-1-2. cut the face that scabbles; 3-2. annular knurl double-screw bolt; 3-3. the transition conical surface; 3-4. double-screw bolt.
Embodiment
Referring to Fig. 1, the utility model comprises knuckle 1, flange plate 2 and wheel bolt 3, and flange plate is fitted on the knuckle, uniform bolt hole on the flange plate, and wheel bolt 3 is positioned at the bolt hole of flange plate, and wheel bolt is used for fastening automotive wheel.
Before improving the common wheel bolt arrangement as shown in Figure 2, as seen from the figure, the position of wheel bolt diameter maximum is bolt head, when wheel bolt withdrawed from by flange plate, bolt head was to produce the key position of interfering with knuckle.
Referring to Fig. 3, Fig. 4, bolt head and knuckle interference problem when withdrawing from wheel bolt for solution, the utility model improves the structure of wheel bolt.As seen from the figure, wheel bolt 3 is comprised of bolt head 3-1, annular knurl double-screw bolt 3-2, transition conical surface 3-3 and double-screw bolt 3-4 successively, and bolt head 3-1 end is provided with circular arc chamfering, and double-screw bolt 3-4 end is provided with chamfering, and the cone angle of transition conical surface 3-3 is 60 °.The cylindrical body that is shaped as of described bolt head 3-1 is cut and have been cut a unfilled corner.Bolt head 3-1 unfilled corner place consists of by cutting to cut inclined-plane 3-1-1 and to scabble face 3-1-2 with its cutting of intersecting, and cuts and cuts the inclined-plane with wheel bolt axis angle α is 40-43 °, and it is parallel with the wheel bolt axis section to scabble face.Unaffected for the use function that guarantees wheel bolt, to cut on the bolt head and scabble face 3-1-2 to wheel bolt axial line distance and annular knurl double-screw bolt radius coupling, bolt head 3-1 thickness B is of a size of the 6.5-7 millimeter.
Referring to Fig. 1, when the utility model uses, the corresponding knuckle 1 in the unfilled corner position of bolt head 3-1 when wheel bolt 3 is installed, like this, when wheel bolt withdraws from, exist to allow more greatly bit space, can not interfere with knuckle, needn't consider again the groove design of stepping down on the knuckle, make things convenient for the knuckle following process, and improve slewing journal structure.
